Sprocket Adaptors or BEC (Bike Engined Cars) Adapters are fully CNC machined from heat-treated chromoly steel.
These are quality items and drilled to fit the commonly used flanges for the propshafts used on these vehicles.
The flanges used are normally Ford or British Leyland standard bolt pattern, propshaft manufacturers use the SAE1140 spec. If you have not got a propshaft yet, your supplier will easily match it. They use your existing sprocket retaining device. Bolt, Circlip or Nut. They can be mounted to float if needed. Bolt holes in adaptors are threaded M8 x 1.25mm so eliminating any clearance problems with the need to use locknuts.
